Just to mention, if you change any stat, it will effect the files and you will have to restart over.
I also own 2 copies of the game, i just copied the folder and installed redacted lan.

Code:
statsetbyname plevel 1-15 // Changes Prestige.
statsetbyname score 420 // Changes your total score.
statsetbyname kills 420 // Changes the amount of kills you have.
statsetbyname wins 420 // Changes the amount of wins.
I guess there could be a way of unlocking camos by changing other stats.

Again, this will give you the "server disconnect" message and you will have to restart.
